Lab 10.1 Working with Helm and Chars

Hello,

I'm having issues following steps in Lab 10.1 Working with Helm and Charts.

First, the command helm repo add ealenn https://ealenn.github.io/charts
leaves me with blinking cursor unless I sudo it.

Next command, ran without sudo returns permission denied error:
open /home/sysadmin/.cache/helm/repository/ealenn-index.yaml: permission denied

Apparently, helm directories under .config and .cache in my home directory belong to the root user. I don't know if this is the consequence of running the first command with sudo but I couldn't run it as a normal user anyway...

Finally, the third command doesn't work with or without sudo. It blocks after the third line, leaving me again with blinking cursor:

history.go:56: [debug] getting history for release tester
Release "tester" does not exist. Installing it now.
install.go:178: [debug] Original chart version: ""

I've tried changing the ownership of helm directories but it didn't change anything.

Any ideas on how to resolve this issue?

Thanks in advance!
